1. Which of the following descriptions are true regarding the management connections on a Cisco router? (Choose three.)
- They are used to connect the router to the rest of the production network.
- They are synchronous serial ports.
- They are used for initial router configuration.
- They are asynchronous serial ports.
- They are accessed using their assigned IP address.
01. Which layer of the hierarchical network design model is refered to as the high-speed backbone of the internetwork, where high availability and redundancy are critical?
- access layer
- core layer
- data-link layer
- distribution layer
- network layer
- physical layer
01. When a collision occurs in a network using CSMA/CD, how do hosts with data to transmit respond after the backoff period has expired?
- The hosts return to a listen-before-transmit mode.
- The hosts creating the collision have priority to send data.
- The hosts creating the collision retransmit the last 16 frames.
- The hosts extend their delay period to allow for rapid transmission.
01. Which two statements describe the benefits of VLANs? (Choose two.)
- VLANs improve network performance by regulating flow control and window size.
- VLANs enable switches to route packets to remote networks via VLAN ID filtering.
- VLANs reduce network cost by reducing the number of physical ports required on switches.
- VLANs improve network security by isolating users that have access to sensitive data and applications.
- VLANs divide a network into smaller logical networks, resulting in lower susceptibility to broadcast storms.
01. Which statement is true when VTP is configured on a switched network that incorporates VLANs?
- VTP is only compatible with the 802.1Q standard.
- VTP adds to the complexity of managing a switched network.
- VTP allows a switch to be configured to belong to more than one VTP domain.
- VTP dynamically communicates VLAN changes to all switches in the same VTP domain.
